Specification of Letters Patent.

Application filed August 12, 1914. Serial No. 856,408.

To all whom it may concern:

Be it known that 1, WILLIAM L. LOGAN, a citizen of the United States,residing at Clarendon, in the county of Donley and State of Texas, haveinvented a new and useful Churn, of which the following'is aspecification. I

The present invention appertains to churns, and aims to provide a noveland improved device of'that character.

It is the object of the present invention to provide a dasher staff orstem engaged through the cover of the churn body or receptacle in apeculiar manner, whereby the dasher or agitator carried by staff or stemwithin the churn body will be simultaneously rotated and reciprocated,the dasher or agitator being of unique construction whereby its rotationand reciprocation .will effectively agitate the contents of th churn forchurning the same.

Another object of the present invention is to provide a novel means for'operatively connecting a non -rotatable reciprocatory handle with theouter or upper end of the dasher staff or stem, in order that the dasherstafi may be effectively and readily operated when the handle is grippedin one orboth hands and reciprocated.

It is also within the scope of this invention, to improve the structuregenerally, whereby its utility will be enhanced, and whereby the devicewill be comparatively simple, durable andinexpensive in construction, aswell as being convenient, practical, serviceable and efficient in itsuse.

NVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

The invention is illustrated in its preferred embodiment in theaccompanying drawing, wherein Figure 1 is a longitudinal section of thechurn, portions being broken away, and parts being shown in full. Figs.2 and 3 are cross sections taken on the lines 22 and 38, respectively,of Fig. 1. Fig. 4 is an enlarged sectional detail of the connec- Idished, as seen in Fig. 1, and provided with a peripheral dependingflange or rim 1 adapted to be slipped snugly into the upper end or mouthof thebody or receptacle 1. The cover 2 may be held in place by anysuitable means to prevent its accidental detachment. A plug 5 of hardmetal is Patented Feb.16, 1915.

soldered or otherwise secured through the center of the top 3 of thecover or cap, and is provided with a slot 6 therethrough. the top 3 ofthe cover being provided with drain apertures 7 adjacent the plug 5through which the milk and cream may flow back into the churn fbody ifit is raised by the I dasher staff.

The dasher staff comprises a twisted bar or strip 8 forming a screw, andwhich is engaged through the slot 6 of the plug 5,

whereby the vertical reciprocation of the dasher staff will rotate thesame.

The dasher or agitator embodies a cruciform or star-shaped plate 9,preferably formed from sheet metal, and having its ends bent angularlyupward to provide the ears 10. The lower end of the dasher staff 8 issecured in any suitable manner through the central portion of the dasheror agitator to carry the vsame. j

In order to operatively connect the handle 11 and dasher staff or screw8, the upper end of the dasher staff is provided with a shank 11 ofcircular cross section and which is externally threaded. The handle 11is preferably constructed of wood and may be of any suitable length, thehandle and dasher staff being coaxial and arranged in verticalalinement. A pair of disks 12 are mounted upon the shank 11' of thedasher staff, and a pair of clamping nuts 13 are threaded .upon theshank 11 to hold the disks 12 together, the nuts 13 seating or bearingagainst the remote faces of the disks 12, and the adjacent faces of thedisks having annular ball races 14. A ring 15 is disposed between theperipheries of the disks 12, and its inner side is provided withopposite ball cones 16 cooperating with the respective ball races 14,and two annular series of ball bearings 17 are disposed between thecomplementing ball races 14 and cones 16 to enable the disks 12 and ring15 to rotate relative to one another.

The ring 15 is secured to the lower end of the handle 11, and to thisend, a pair of arcuate plates 19 are secured to opposite sides of thehandle 11 adjacent its lower end, by means of a rivet or other securingmember 20 engaged through the plates 19 and the lower end portion of thehandle, and the plates 19 are provided with depending arms 21 offsetaway from each other to provide a fork. The lower ends of the arms 21are bent angularly toward one another, as at 22, and are engaged withinslots or recesses 23 provided in diametrically opposite portions of thering 15. The arms 21 may be soldered or otherwise secured to the ring15. In this manner, the ring 15 is rigidly secured to the lower end ofthe handle 11, in spaced relation therewith, and the ring 15 beingdisposed between the two sets or series of ball bearings 17, will enablethe dasher staff to be reciprocated with the handle, although the dasherstaff is free to rotate. The nuts 13 hold the disks 12 together, tothereby prevent their excessive separation, except when the device isseparated.

The present device may be employed for churning purposes, in the usualmode, it being noted that when the dasher staff is reciprocated, it willbe rotated to thereby impart both a reciprocatory and rotatory movementto the dasher or agitator for thoroughly agitating and churning thecontents of the body or receptacle 1. Ihe peculiar formation of thedasher or agitator is of advantage in properly agitating and churningthe contents of the churn body, and for enabling the butter to bereadily lifted from the churn body with the dasher. The plug 5 providesa durable wear member for the dasher staff, it being noted that thecover or cap is provided with the drain apertures 7 adjacent the plug 5whereby any milk and cream raised through the slot 6 with the dasherstaff, may flow back into the 1,12e,ese

dasher staff, to enable the dasher staff to rotate freely as it isreciprocated.

Having thus described the invention, what is claimed as new is 1. In achurn, a churn body, a cover therefor, a twisted dasher staff engagedthrough the cover, a dasher carried by the dasher staff Within the churnbody, a pair of disks mounted upon the upper end portion of the dasherstaff and having annular ball races in their adjacent faces, a handle, afork attached to one end thereof, a ring secured to the ends of the forkarms and disposed between the said disks, the inner side of' the ringbeing formed with ball cones, and ball bearings disposed between therespective ball cones and ball races.

2. In a churn, a churn body, a cover therefor, a twisted dasher staffengaged through the cover, a dasher carried by the staff within thechurn body, the dasher staff having a shank at its upper end, a pair ofdisks mounted upon the said shank, a pair of nuts threaded upon theshank to hold the disks against separation, a handle, a ring attached tothe handle and disposed between the said disks, and anti-frictionalbearings disposed between the said ring and disks.

In testimony that I claim the foregoing as my own, I have hereto affixedmy sig nature in the presence of two witnesses.
